Ink jet recording method and liquid dispersant

摘要

An ink jet recording method including attaching a liquid dispersant in which an amphoteric polymer containing a core portion having a cation group and a shell portion having an anion group that covers the core portion is dispersed in a dispersing medium to a recording medium and discharging and attaching cationic ink containing a coloring material and water to the surface of the recording medium to which the liquid dispersant is attached.

主权项

1. An ink jet recording method comprising the steps of:
attaching a processing liquid in which an amphoteric polymer comprising a core portion having a cation group and a shell portion having an anion group that covers the core portion is dispersed in a dispersion medium to a surface of a recording medium; and discharging and attaching cationic ink comprising a coloring material d water to the surface of the recording medium where the processing liquid is attached, wherein an amount of the processing liquid attached to the recording medium as measured by a dynamic scanning absorptometer is from 10 ml/m2 to 25 ml/m2 for a contact time of 100 ms, and wherein the step of attaching a processing liquid is performed prior to the step of discharging and attaching cationic ink.
